The Dealer Model
Factory-built home manufacturers do not sell directly to consumers. You purchase through an authorized dealer — which is the role ModularHomes400.com plays. The dealer manages model selection, permits, delivery, foundation engineering, and warranty resolution, plus the deregistration paperwork for CSA Z240MH conversions to real-property title.
